It should be simple to resolve expressions like this at compile time:

  if (@1 == "foo" && $2 == 42)
    println("clichéd arguments found!")

Beware of side effects though -- "if (0 && foo())" can always be removed, but
"if (foo() && 0)" might need to call foo() even though its return value doesn't
matter.
